Our invention has reference to a water holder for an animal cage and to supporting means for the water holder.

Reference is to be had to the accomp anying.

drawings forming part of this specification, it being understood that the drawings are merely illustrative of one example of the in-, vention. v Figure 1 is a perspective view of an animal 10 cage embodying our invention;

Figure plane indicated by the lines 2--2 of Figure 1; Figure 3 is a perspective view of a water holder; V

Figure 4 is a vertical section on the line 4-4 of Figure 2; p Figure 5 is a transverse vertical section on the line 55 of Figure Figure 6 is a perspective view of the drawer o for holding the urinal discharges of the animal; and V Figure 7 is a sectional view showingcertain details of the water tray or holder adjusting means, a portion of the tray or holder In carrying out our invention inaccordance with the illustrated example, the body of the cage 10 is given a general boX-likeform and has at the upper portion side panels 110 of 210 also of wire mesh or other openwork.

At the front is a duplex door, there being a sheet metal door 11 and a wire mesh door 12, said doors having each a suitable fastening means 13 at the sides. The sheet metal door 11 has an angular upper edge 14: offset laterally inward against which the wire mesh door 12 closes at the bottom edge, the upper edge of the doorclosing against the angular upper edge at the top of the cage body 10.

A water holder 15 is carried by the door 11 at the inside. Said water holder 15' is formed with tubular vertical: guides 115 which are sleeved on threaded rods 16 held by eye-bolts 17, the upper end of each rod 16 having a collar 18 beneath the head of the bolt 16 to rest on the upper eye-bolt 17. A nut 19 is rigid with the water tray or holder 15 andis threaded on to the rod 16. Said rod 16 has a squared or non-circular portion 2 is a horizontal section taken in a wire mesh or other op-enwork and rear panels 1 as will be seen, isreadily adjustable to place its contents within comfortable reach of the 116to promotejconvenience inturning-the 7 V rodso that the threaded engagement of the same with the nut 19 willcause the nut to g travel upv or down on said rod and thereby raise or lower the water holder 15 to a height suited to the size of theiparticularanimal under'observation in the cage and without liability of the'water being contaminated by eianim l.v r s i A a se bottom or floor 20hr the animals support is; provided and formed preferably of wiremesh or equivalent openwork ma terial so that the yurinal discharges from the animal will freely pass therethrough,

The false bottom 20 rests on aled e 21. on

andthe possible contamination of the urine by such matter is prevented.

We would; state furthermore that while the illustrated example constitutes apractical embodiment of our invention, we do not limit d a ourselves strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from as defined in the appended claims. a 4

[We claim:

L :1.'In an animal cage, a door, a vertical rodon the door, coacting means onthe door and rodsupporting said rod-forturning movement but preventing axial-movement thereof, and a receptaclecarried by said rod and vertically adjustable thereon by turning said rod.

' 2. Inananimal cage, a water-holder, a vertical rod having 'a threaded portion, means connected with the upper and lower-ends of the rod turnably supporting the rod and preventing axial movement thereof, and a nut rigid with the water holder and in engagement with the threads of said rod, the turn-; ing ofthe rod serving to cause the nut to travel for'raising or lowering the water holder.
